AM50065A43-A Equivalent & Substitute Parts

Part Overview

The AM50065A43-A is a SPST-NO (Single Pole Single Throw - Normally Open) snap-action switch manufactured by Panasonic Electric Works. This chassis-mount switch is rated for 100mA at 125V AC and 30V DC, featuring a lever with roller actuator and solder/quick-connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for design continuity and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM50065A43-A requires matching the following critical parameters:

• Circuit configuration: SPST-NO topology
• Switch function: Off-Momentary operation
• Mounting interface: Chassis mount with compatible actuator geometry
• Termination compatibility: Quick-connect or solder-compatible terminals
• Electrical ratings: Current and voltage capacity sufficient for the application
• Operating temperature range: Functional across specified thermal envelope
• Mechanical durability: Cycle life appropriate for the intended duty cycle

The Crouzet 83265826 qualifies as a functional substitute based on identical circuit topology (SPST-NO), matching switch function (Off-Momentary), compatible chassis-mount design, and quick-connect termination. While electrical ratings exceed the original specification, this represents a design upgrade path rather than a limitation.

Parameter Comparison

Engineering Selection Recommendations

The Crouzet 83265826 is an active-production substitute for the obsolete AM50065A43-A. Both components share identical circuit topology and switch function, with compatible chassis-mount and quick-connect interfaces.

The Crouzet part provides enhanced electrical performance (5A at 250V AC versus 100mA at 125V AC), supporting applications requiring higher current or voltage capacity. The extended operating temperature range (-20°C to 125°C) accommodates broader thermal environments compared to the original specification (-25°C to 105°C).

Mechanical life differs significantly: the Crouzet part is rated for 1,000,000 cycles versus 10,000,000 cycles for the Panasonic original. Applications requiring extended cycle life should evaluate this parameter against duty cycle requirements.

Both components carry identical ECCN (EAR99) and HTSUS (8536.50.7000) classifications, ensuring consistent regulatory treatment. The Crouzet part is RoHS Compliant and REACH Unaffected, meeting current environmental compliance standards.

Terminal geometry requires attention: the Crouzet uses 0.250" (6.3mm) quick-connect terminals versus the Panasonic's 0.187" (4.7mm) configuration. PCB or harness redesign may be necessary to accommodate this dimensional difference.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 83265826 directly replace the AM50065A43-A without circuit modification?

A: The Crouzet part is functionally equivalent in circuit topology and switch operation. However, terminal geometry differs (0.250" versus 0.187" quick-connect), requiring harness or PCB connector redesign. No circuit modification is necessary if termination interfaces are updated.

Q: What is the primary reason for substitution?

A: The AM50065A43-A is obsolete. The Crouzet 83265826 is an active-production alternative with identical SPST-NO circuit configuration and Off-Momentary function, ensuring design continuity.

Q: Are the electrical ratings compatible with my application?

A: The Crouzet part exceeds the original electrical specifications (5A at 250V AC versus 100mA at 125V AC). If your application requires exactly 100mA at 125V, the Crouzet part will operate safely at reduced load. Verify that your circuit design does not depend on the lower current rating for protective functions.

Q: What is the impact of the different mechanical life ratings?

A: The Crouzet part is rated for 1,000,000 cycles versus 10,000,000 cycles for the Panasonic original. For applications with high-frequency switching (>100 cycles per day), evaluate whether 1,000,000 cycles provides sufficient service life. Calculate expected cycle count over the product's intended operational lifetime.

Q: Are there compliance or regulatory differences?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.7000) classifications. The Crouzet part is RoHS Compliant and REACH Unaffected, meeting current environmental standards. No additional compliance review is required for substitution.

Q: What is the operating temperature compatibility?

A: The Crouzet part operates across -20°C to 125°C, compared to the original -25°C to 105°C. If your application requires operation below -20°C, the Crouzet part is not suitable. For applications within -20°C to 105°C, both parts are compatible.
